my exterior light keeps shorting out.
Answer Mark, Are you sure the cavity light isn't being used as a "night light", or left on for extended periods of time. The 120 VAC 10 watt light bulb is not designed for extended periods of use, and will "burn out" in minimal amounts of time. Otherwise, You'll need to check the blue/black, and white wires from the door hinge to the dispenser light switch and from the switch to the light socket, yellow/black wire, for frayed wires and loose connections.
are maytag and whirpool parts interchangeable? My light bulb is the same part number.
Answer Mermaid, Yes, it is possible to have the same part numbers, Maytag is now a subsidiary of Whirlpool Corp. Some parts are "universal" across a lot of product lines and brands.
